N-acetyl-D-galactosamine reacts with which lectin?

N-acetyl-D-galactosamine is a specific sugar that is known to react prominently with the lectin derived from Dolichos biflorus. Lectins are proteins that bind carbohydrates specifically, and the binding of N-acetyl-D-galactosamine to Dolichos biflorus lectin is a well-documented interaction that is often utilized in blood group serology to identify certain blood types.

In contrast, the other lectins mentioned have different specificities and do not interact with N-acetyl-D-galactosamine in the same manner. Arachis hypogaea, for instance, is primarily known to react with the sugar D-mannose and certain galactosyl residues, while Salvia sclarea exhibits a preference for terminal galactose residues rather than N-acetyl-D-galactosamine. Ulex europaeus, on the other hand, is known to react with the Lewis antigen and L-fucose and does not have a strong binding affinity for N-acetyl-D-galactosamine.

Understanding these specific interactions is crucial in immunology and serology, especially when it comes to determining blood types and compatibility in transfusions, as well as in various
